Dredging and Marine Odd Jobs, Dredge Edition (Nov. 29)

Two disparate but nonetheless intriguing segments fill out this episode. First, Jon Chang and Kate Yandell talk about fracking. Second, Kelly Slivka interviews a marine biologist about a job off the radar: observing for marine life during dredge operations. 

Food, etc. (Nov. 22)

_Though this episode was food-themed at conception, it turned into more of a "drink" episode. Typical. First, Jon Chang asks some vendors at NovemBEER to talk to about their brews. Then Rose Eveleth and Colm Kelleher discuss a different kind of brew: coffee made from poo. Lastly, Kelly Slivka switches our gears to find out why DNA is called DNA.
